eRa Cellular

Of course, cell phone Bluetooth usage is not limited to just headsets–you can also use Bluetooth to stream music wirelessly, connect to the Web, transfer files, and more. In addition to connecting a cell phone to a headset, Bluetooth is used to connect PCs to keyboards and mice, handhelds to other handhelds, and cell phones to computers.

The process of connecting devices via Bluetooth starts with pairing, a procedure wherein a Bluetooth-enabled phone and another Bluetooth device search for and recognize each other. Bluetooth does have limitations, however. Also, you can connect only devices that have compatible versions of Bluetooth. Though Bluetooth itself may be easy to understand, choosing a Bluetooth headset for your phone isn’t so simple.

The number of Bluetooth headsets continues to grow rapidly. Most Bluetooth headsets have basic call features like the ability to answer and reject calls, last number redial, and so forth. A Bluetooth profile is an interface or a behavior through which different Bluetooth devices can communicate with each other. The most common Bluetooth profile in cell phones is the Headset profile which supports the use of standard mono headsets for making calls.

Here’s a list of the more frequently used Bluetooth profiles in cell phones, as described by the Bluetooth SIG: Also widely known as the stereo Bluetooth headset profile, A2DP allows for a dual-channel audio stream through a stereo headset. For Bluetooth enabled devices, only connection-oriented OBEX is supported.
SAP allows devices such as car phones with built-in GSM transceivers to connect to a SIM card in a Bluetooth-enabled phone. Most mono Bluetooth headsets can be grouped into two categories: models with a boom and models without. A more recent Bluetooth headset design innovation has been the inclusion of LED screens.

Stereo Bluetooth headsets generally look and feel a lot like wired music headphones. A few Bluetooth headsets combine several different functionalities into one design. The Kyocera Wireless Bluetooth headset with Speakerphone comes with–you guessed it–a little portable Bluetooth speakerphone.

Bluetooth accessories for your cell phone aren’t limited to just headsets. One of the up-and-coming categories for mobile Bluetooth accessories is the Bluetooth speakerphone. There are also a few devices that combined the Bluetooth headset with a speakerphone. The Kyocera Wireless Bluetooth headset with Speakerphone is one such combo; the headset is inserted into the speaker slot to activate the speakerphone function.
